How to create basic Stata estimation commands
培训时间:11 August 2020 11:00 AM CT
本次网络研讨会介绍如何在Stata中编写自己的估算命令。本次网络研讨会是在上一次网络研讨会讨论How to create basic Stata commands的基础上,重点讨论用于模型拟合的命令。
Chuck将首先向您展示如何创建一个将Stata变量转换为矩阵的命令,如何使用矩阵计算来拟合模型,以及如何在标准Stata输出中显示结果。然后,您将看到如何使用ml较大化似然函数。了解如何自动使用Stata估计命令的常见功能。Chuck还将演示如何轻松地调整命令以适应复杂的测量数据。
Chuck Huber is the Associate Director of Statistical Outreach at StataCorp and an adjunct associate professor of biostatistics at the Texas A&M School of Public Health. In addition to working with Stata's team of software developers, he produces instructional videos for the Stata YouTube channel, writes blog entries, develops online NetCourses, and gives talks about Stata at conferences and universities. Most of his current work is focused on statistical methods used by psychologists and other behavioral scientists. He has published in the areas of neurology, human and animal genetics, alcohol and drug abuse prevention, nutrition, and birth defects.
Survival analysis using Stata
培训时间:25 August 2020 11:00 AM CT
生存分析使我们能够测量发生感兴趣事件的时间。例如,您可能会比较服用安慰剂的人和服用新药物的人的死亡时间。您也可能在衡量就业或破产的时间。分析此类数据时会出现一些复杂情况:可能无法观察到感兴趣的事件,个体可能在不同的时间进入研究,并且在整个研究过程中可能无法连续观察到某些个体。这些固有的复杂性导致了用于分析这类数据的各种模型。
本次研讨会,Gabriela Ortiz,应用统计学家,她将展示Stata用于生存分析的专门工具。她将向您介绍Stata中可用于分析生存时间数据的汇*计、图表、模型和诊断。您将学习如何获得平均生存时间,发病率 以及执行平等性检验。您有兴趣把生存建模变为协变量的函数吗?Gabriela将向您展示如何拟合不同的回归模型并调整组内相关性。您将了解到,即使您的数据有竞争性的失败事件,或者当您感兴趣的事件的确切时间未知时,您仍然可以在Stata中分析您的数据。您还将看到如何可视化模型的结果并以图形方式评估模型拟合。
Gabriela Ortiz is an Applied Statistician at StataCorp. She holds a bachelor's degree in psychology from the University of California, Davis, and a master's degree in economics from California State University, Long Beach. Gabriela is a primary author of Stata's reporting manual and has contributed to the development of each of the reporting features. She also developed and regularly teaches Stata's introductory webinars.
